Abominable Assault by Stop

A note from Stop

Mainly squids. Initially a lot more Squid IIs and Squid IIIs but with period Squid Is. Getting to both Level 3 and Level 4 isn't easy. Lasts up to around 10 minutes if you achieve Level 4. Surviving over 10 minutes is the goal.Not tried to see if staying at Level 3 and using homing daggers can get you further. Also has a rapid shrink that ends after 5 minutes, as the end loop starts.
